LEDs, or light emitting diodes, have been around for decades but factors such as reduced costs, improved luminous efficacy and faster switching are leading to widespread use of this technology in the commercial, residential and industrial lighting market.

he solid state lighting (SSL) revolution is well underway. The market adoption of the SSL technology, used in diverse applications including general lighting, traffic signals and automotive lighting, is increasing at a record pace around the world. The US Department of Energy expects LED lighting to represent 74% of US general illumination lumen-hour sales by 2030. “By 2027, widespread use of LEDs could save about 348 TWh, compared to no LED use, of electricity: this is the equivalent annual electrical output of 44 large electric power plants (1000 mW each) and a total savings of more than $30bn at today’s electricity prices.” LEDs and OLEDs (organic LEDs), both forms of solid state lighting, are set to transform lighting as we know it, says Bryan Douglas, CEO, Lighting Council of Australia. “Solid state lighting is a highly adaptable technology, capable of brilliant and variable colours, is energy efficient and has a long lifetime, making it ideal for practically all forms of lighting.”

LEDs and lighting controls While all the current excitement is about LEDs, a quieter revolution is going on with lighting controls, says Douglas. “Modern lighting controls have enormous potential to save energy. Being electronically based, they are also highly suited to use with LEDs. In fact, the full potential of LEDs may only be realised with sophisticated

www.ECDsolutions.com.au

lighting controls. We can expect to see far greater use of lighting controls in the future.” Mark Centofanti, product manager lighting, Clipsal by Schneider Electric, shares a similar view. Lighting accounts for around 11% energy use in buildings, and lighting controls not only help home and business owners improve energy efficiency but they also help cut costs, he says. Currently most lighting controls are mounted on the walls - in the next few years, these controls will move into the lights themselves, he adds. It is all about the transition from conventional to LED lighting, and with it a dramatic increase in the take-up of lighting control technologies, says Richard Shepherd, marketing manager, Philips (Australia). “We’re seeing the switch from lighting to lighting solutions across the entire spectrum of projects, from homes to offices to industrial installations and everything in between.” Due to the rapid take-up of LED, Philips is anticipating energy-efficient technology to make up about 50% of the company’s global lighting sales by 2015, up from 25% last year.

Contractors’ role Electrical contractors play a key role in further driving the uptake of the solid state lighting technology. “Because of the variability in quality, it is important that they understand the attributes of any solid

state lighting product before selecting or recommending it,” says Douglas. When recommending lighting fixtures, contractors need to be mindful that they are meeting the needs of the end user, using products that are suited to the space and/or the application, as well as meeting Australian standards, suggests Shepherd. “It is important for contractors to always compare like for like when making product recommendations. There are a number of LED-only, non-traditional suppliers entering the LED market so contractors need to factor LED quality, optics, heat management and system efficiency into their decision making. “Take a consultative approach with each customer when recommending lighting. Lighting has an enormous part to play in how we engage with a space so consider how you are satisfying a ‘light’ requirement rather than a ‘lighting’ requirement.”

as a course in Electrical Energy Efficiency 21876VIC, according to NECA. Following training, contractors can apply for accreditation as an EcoSmart Electrician. The association also runs a BCA Lighting (Commercial) course to help contractors understand the Building Codes of Australia. Candidates interested in enrolling in this course must have completed the Lighting Module of EcoSmart Electricians training or Lighting for Living course or equivalent. Separately, MEA has recently launched the Master Electrician Energy Efficiency course for those wanting to build their business by entering the energy-efficiency market. “During the course you will learn to prepare, plan, carry out and complete the implementation and monitoring of environmental and sustainable energy management policies and procedures,” according to MEA.

Stay enlightened

Training and education will not only help contractors acquire knowledge and grow their business, but it can also go a long way in getting rid of the counterfeit products from the market. In any industry where there is a rapid transition from one technology to another, it is not uncommon for there to be issues, says Shepherd. “End users have and should have certain expectations when it comes to LED lighting. One way to respond to the issue of counterfeits is for contractors to always compare like for like when making product recommendations.” “There are a lot of people buying lights on the internet and reselling them. They are causing some confusion in the marketplace and there is a lot of uncertainty about the quality of these components,” says Steve Cahill, general manager, en-

Electrical contractors who keep up to date with the latest lighting trends and regulations by regularly visiting government, industry and lighting manufacturer websites as well as supplementing knowledge through upskilling courses will be well placed to support the update of new technology, says Shepherd. Industry associations such as National Electrical Contractors Association (NECA) and Master Electricians Australia (MEA) offer various courses covering LED technology and energy efficiency. In 2012, NECA EcoSmart Electricians reviewed its training program and updated it to include new technologies such as lighting controls and energy management systems and the rapidly evolving LED technology market.

Fighting the fakes

Lighten Australia. This is causing a lot of turmoil and is giving the industry a bad reputation, he says. The proliferation of low-quality, poorperforming products has led Lighting Council Australia to introduce a certification program for LEDs - the Solid State Lighting Quality Scheme, said Douglas. A minimum set of critical parameters is reported by participating suppliers to accurately reflect the performance of their products. The scheme participants provide test reports or other evidence verifying their claims. Lighting Council Australia registers the product on a database on its website (www. lightingcouncil.com.au) and authorises use of a label indicating conformance to the parameters. Douglas suggests that if contractors are in doubt they should look for the Solid State Lighting Quality Scheme label or at the very least ensure that the product is from a reputable supplier. They should look for a warranty period of at least three years and preferably longer.

Government initiatives The government has introduced minimum energy performance standards (MEPS) on a range of lighting products over the past 15 years or so, notes Douglas. While the Australian Government was the first in the developed world to phase out incandescent GLS lamps, to date, however, there is no regulation stipulating the energy-efficiency requirements of LEDs, he adds. “This will change, however, with the government foreshadowing a number of measures to ensure that LEDs meet MEPS and quality requirements. Lighting Council Australia will work closely with the government on implementation.” Other initiatives that will encourage the move to more efficient lighting technologies include: voluntary take-up of Green Star Certification and mandatory CBD requirements, combined with government incentives such as IPART (Independent Pricing & Regulatory Tribunal of NSW) and VEET (Victorian Energy Efficiency Target) to create energy-saving certificates for energy-efficient projects (lighting retrofits), says Shepherd.

BUSINESS ADVICE

TIPS TO IMPROVE BUSINESS EFFICIENCY Jodie Curtis

In the current economic climate, it is more important than ever for businesses to improve efficiency and strengthen growth. Below are some tips from accounting firm HLB Mann Judd to help businesses operate efficiently.

here are a number of steps that business owners and managers can take to increase efficiencies, which should result in improved profitability for their business. These involve both reducing or controlling costs, and ensuring a better marketing focus to increase sales. 1. Key performance indicators: KPIs are those elements that the business has identified as vital to its success. They could include: sales figures; customer retention; aspects of the manufacturing process; or turnover. Calculating and reporting KPIs in a timely manner provides a snapshot of actual business performance, allowing any issues to be identified before they have a major effect on the bottom line. 2. Business plan: It’s important for the future success and growth of a business to invest the time in creating a business plan. Business planning allows a vision for the business to be created and measurable goals established so that the vision can be achieved. Benefits include: clarity and focus in the direction of the business; greater ability to make continuous improvements and anticipate issues; greater confidence in decision-making. Those who already have a business plan should review it regularly and update as needed. 3. Cash flow: Creating cash flow forecasts allows better understanding of when money is coming in and going out, so that any delays or shortfalls can be managed. Focusing on the following will help with managing cash flow: • Debtors - invoice promptly, invoice progress payments, offer discounts for prompt payment, offer different payment options and follow up outstanding debtors • Creditors - negotiate credit terms, take advantage of discounts, do not pay earlier than required. • Inventory - keep accurate and timely records, replace slow-moving products, and mark down dead inventory for quick sale. 4. Customer retention: Encourage customers to keep coming back by ensuring their needs are met and providing quality service. Do what you said you would do; communicate regularly; give the customer the opportunity to provide feedback; implement a loyalty or referral program. Effective cross-selling and bundling techniques can increase the average dollar spend by each customer. 5. Best practice: If the business’s processes were developed many years ago and the comment “this is the way it’s always been done” sounds familiar, it may be time to review processes. Best practice

8 ECD SOLUTIONS - JULY/AUG 2013

means adopting the best ways of working to achieve business objectives, for instance by: keeping up to date with what competitors are doing and benchmarking against other successful businesses; encouraging a culture of innovation and creativity; making good use of technology. 6. Supplier arrangements: There are often opportunities to negotiate better terms with suppliers. Businesses should review current supply contracts and take advantage of any discounts for prompt payment or extended payment terms. They should also seek competitive suppliers and get comparative quotes. 7. Banking relationships: Meeting with the business’s banker to discuss current facilities and business position enables a better understanding of the terms of current facilities as well as other available facilities. For example, there may be better interest rates available, reduced fees, more convenient ways to pay, or the availability of credit to assist with cash flow. 8. Employees: Engaged employees are more productive and committed to a business, and this can have a positive impact on business performance. Businesses could improve employee engagement through: effective communication; mentoring programs; delegating responsibilities; providing opportunities for advancement; empowering employees. 9. Go green: Adopting environmentally friendly processes is good for the environment and may also lower operating costs. Strategies include: implementing paperless procedures such as electronic filing of emails or electronic billing and banking; printing double-sided and re-using scrap paper; switching off lights and computers at the end of each working day; substituting incandescent lamps with compact fluorescent lamps; installing timers or thermostats to maximise efficiency of air conditioning. 10. Productivity: There are only so many hours in a day and therefore productive days are important for efficiency and success. Mark Twain said “Eat a live frog first thing in the morning and nothing worse will happen to you the rest of the day.” Business owners and managers should develop the habit of “eating a frog” by starting on the most difficult task (or the task you are most likely to procrastinate on) and persevering until it is complete. Clean and sort the email inbox to save valuable time, write down a task list, prioritise based on importance, complete unfinished work and consider delegation of tasks to others.

SENSORS

WIRELESS SENSORS FOR REMOTE INFRASTRUCTURE MONITORING

As thousands of bridges, parking garages and other structures age, improved methods for detecting deterioration could save lives and prevent economic disruption.

esearchers at the Georgia Institute of Technology are developing novel technology that would facilitate close monitoring of structures for strain, stress and early formation of cracks. Their approach uses wireless sensors that are low cost, require no power, can be implemented on tough yet flexible polymer substrates, and can identify structural problems at a very early stage. The only electronic component in the sensor is an inexpensive radiofrequency identification (RFID) chip. Moreover, these sensor designs can be inkjet-printed on various substrates using methods that optimise them for operation at radio frequency. The result would be low-cost, weather-resistant devices that could be affixed by the thousands to various kinds of structures. “For many engineering structures, one of the most dangerous problems is the initiation of stress concentration and cracking, which is caused by overloading or inadequate design and can lead to collapse - as in the case of the I-35W bridge failure in Minneapolis in 2007,” said Yang Wang, an assistant professor in the Georgia Tech School of Civil and Environmental Engineering. “Placing a ‘smart skin’ of sensors on structural members, especially on certain high-stress

www.ECDsolutions.com.au

hot spots that have been pinpointed by structural analysis, could provide early notification of potential trouble.” Wang is collaborating with a team that includes Professor Manos M Tentzeris of the School of Electrical and Computer Engineering and Roberto Leon, a former Georgia Tech professor who recently moved to Virginia Tech. The work is supported by the Federal Highway Administration. The Georgia Tech research team is focusing on wireless sensor designs that are passive, which means they need no power source. Instead, these devices respond to radio-frequency signals sent from a central reader or hub. One such reader can interrogate multiple sensors, querying them on their status at frequent intervals. The researchers’ approach utilises a small antenna mounted on a substrate and tuned to a specific radio frequency. This technique enables the antenna itself to function as a stress sensor. As long as the structural member to which the antenna/sensor is affixed remains entirely stable, its frequency stays the same. But even a slight deformation in the structure also deforms the antenna and alters its frequency response. The reader can detect that change at

SENSORS

once, initiating a warning months or years before an actual collapse. “A key benefit of this technology is that it’s completely wireless,” Wang said. “It doesn’t require a battery and you don’t have to climb around on bridges running long connecting cables.” The research team has developed a prototype strain/crack sensor that has been successfully tested in the laboratory, Wang says. The simple device consists of a small piece of copper mounted on a polymer substrate, plus a 10-cent 1 x 1 mm RFID chip. The chip is used to distinguish each individual sensing unit from others. The simple sensor architecture allows it to be made at very low cost and to potentially be deployed in large quantities on any bridge.

Inkjet-printed circuits More sophisticated designs are in the works. Tentzeris’ team is tackling an approach that produces strain sensors using different applications of inkjet printing technology. One such design uses a silver-nanoparticle-based ink that is applied to a flexible or semiflexible substrate, says Rushi Vyas, a PhD student working with Tentzeris. The ink lays down a structure that can change properties in response to strain. A second approach involves the use of inkjet-printed carbonnanotube-based structures, Vyas says. In this case, the nanotubes themselves produce an altered response when subjected to deformation. In laboratory testing, the team’s prototype sensors have demonstrated high sensitivity in response to even slight changes in metal structures, Wang says. The sensors have been able to reliably detect a degree of deformation change as low as tens of microstrains (one microstrain equals 0.0001%, or one part per million) and they can continuously monitor stress accumulation until the metal develops a severe crack. One issue still being addressed is the capacity of the passive sensor to respond to a reader. A reader transmits a radio-frequency beam to a sensor, which utilises that received energy to reflect a signal back to the reader. But this technique can be rather inefficient, Vyas says. A signal from a reader might travel 15 m, yet the sensor’s response might

only travel back 3 m. One issue is that readers are limited by FCC regulations, which govern how much power can be transmitted to the sensor.

Increasing the power What’s needed are ways to supply a sensor with a power source that would increase the range of the response signal. Batteries are not preferred because they can be undependable and require periodic replacement. A Georgia Tech team that includes Tentzeris and Vyas is researching ways to gather power from ambient or electromagnetic energy in the air, such as television, radio, radar or other manmade signals found in Earth’s lower atmosphere. Scavenging experiments utilising TV bands have already yielded power amounting to hundreds of microwatts. Multiband systems are expected to generate one milliwatt or more - enough to operate some small electronic devices such as low-power wireless sensors. Tentzeris noted that smart-skin technology may soon help to enable a broad range of applications. These could include not only real-time stress monitoring in bridges, factories and buildings, but also new and extremely lightweight aircraft with self-sensing/selfdiagnostic capabilities, and battery-free methods for monitoring structures after major disasters such as earthquakes or hurricanes. “The wireless strain sensor could prove to be an effective, low-cost and easy-to-scale solution to a very important need,” Tentzeris said. “A simple device - consisting of an antenna, an inexpensive RFID chip and some power-boosting technology - could quietly monitor at-risk structures for many years and then send back a real-time warning if there’s suddenly a problem.” This research was reported in IEEE Antennas and Wireless Propagation Letters, Volume 11, 2012, and International Journal of Smart and Nano Materials, Volume 2, 2011. Parts of this research were also presented at ASME 2012 Conference on Smart Materials, Adaptive Structures and Intelligent Systems (SMASIS) and several other conferences.

ELECTRICAL EQUIPMENT FOR MACHINE SAFETY © www.sxc.hu/sougata

Morand Fachot, IEC etech

Equipment such as machine tools and robots has been used extensively in a variety of manufacturing sectors for decades. Individuals working with, or in close proximity to, these machines are reliant on their safe operation for protection, as are nearby installations.

ny industrial machine that may cause accidents must be safeguarded. The addition of electrical equipment such as electromechanical sensors and switches that can activate safeguarding mechanisms - to keep operators at a safe distance or halt operation automatically in case of danger - can prevent accidents occurring or reduce their severity. Among the many IEC TCs that prepare International Standards for these devices, IEC TC 44 is notable as it aims to protect users from the risks posed by all kinds of machines by preparing standards for electrical equipment associated with machinery. Industrial machines may be powered by kinetic, electrical, hydraulic or pneumatic energy. Whatever the source, there are often similar safety issues. By adding electrical equipment, individuals can be prevented from coming too close to, or interfering with, machinery in operation. The addition also enables machines to be shut down in case of malfunction or failure. The added equipment may help prevent injuries or even death occurring. International Standards developed by TC 44 include general and specific requirements for different types of electrical equipment used with machines. They may concern indication, marking and actuation - including visual, acoustic and tactile signals - as well as the location and operation of actuators. TC 44 International Standards also cover ESPE (electro-sensitive protective equipment), such as various kinds of AOPDs (active optoelectronic protective devices) and other equipment designed to detect human presence. TC 44 was created in 1957 to develop safety-related standards for electrical equipment associated with industrial machines, particularly machine tools and large machinery. Its present activities comprise three main elements: preparation of International Standards relating primarily to non-portable electrotechnical equipment and machinery systems, including machinery assemblies; preparation of International Standards for electrotechnical equipment and systems relating to the protection of persons from specific machinery hazards, taking into account a

coordinated systems approach; coordination with ISO (International Organization for Standardization) on all matters concerning the safety of machinery. The following technology tends have an impact on the TC’s work: safety functions; functional safety, including software; development and application of smart sensors; remote diagnostics of plant and equipment; use of communication networks (bus systems) for machinery safety-related control functions; cableless control; switching devices on semiconductor basis. Market trends also drive safety considerations. Industrial machines are not produced, traded and operated in a single country but globally. International customers expect to be presented with common solutions that can be used in several countries. This allows them to harmonise their sites and plants globally to rationalise their production procedures and to save costs through the globally organised purchase of production equipment. These TC 44 International Standards are increasingly applicable worldwide. For developing International Standards covering a wide range of equipment, TC 44 is organised into 4 WGs (Working Groups), one Project Team that looks at requirements for the electrical equipment for machine tools, 7 MTs (Maintenance Teams) for existing standards, and a JWG (Joint Working Group) with ISO TC 199: Safety of machinery. TC 44 aims to keep its International Standards up to date to reflect new and changing technologies and to ensure they are state of the art at the time they are drafted. It states that it will work with ISO TC 199 to merge IEC 62061 and ISO 13849-1 into a dual logo IEC/ISO standard. As industrialisation extends to more and more countries, and automation is introduced to all sectors, the safety of industrial machines, which are traded on a global scale, becomes ever more important. The work of IEC TC 44 experts, which is constantly being updated and expanded, will, therefore, remain essential to ensure that the safe operation of machinery throughout the world continues to increase.

DATA CABLING

TOP OF RACK VERSUS STRUCTURED CABLING

There is no one-size-fits-all solution for data centre cabling. To make the decision-making process easier for data centre professionals, CIOs and IT managers, the Communications Cable and Connectivity Association details the pros and cons of structured cabling versus top of rack.

ata centre cabling configuration choices are impacted by a number of factors including the need to lower power consumption and ensure efficient cooling of critical equipment, as well as by budget constraints and management structure. Below are some factors to consider.

System design and topology When the first data centres were built, end user terminals were connected via point-to-point connections. This was a viable option for small computer rooms with no foreseeable need for growth or reconfiguration. As computing needs increased and new equipment was added, these point-to-point connections resulted in cabling chaos with associated complexity and higher cost. In response, data centre standards like TIA-942-A and ISO 24764 recommended a hierarchical structured cabling infrastructure for connecting equipment. Instead of point-to-point connections, structured cabling uses distribution areas that provide flexible, standards-based connections between equipment, such as connections from switches to servers, servers to storage devices and switches to switches. With todayâ&#x20AC;&#x2122;s high-performance servers and virtualisation, more applications can be delivered from a single rack of servers than

ever before. In response, several switch manufacturers recommend a top of rack (ToR) configuration where smaller (1RU to 2RU) edge switches are placed in the top of each server rack (or cabinet) and connect directly to the servers in the rack via short preterminated small form factor pluggable (eg, SFP+ and QSFP) twinaxial cable assemblies, active optical cable assemblies or RJ45 modular patch cords. ToR significantly increases the number of switches and reduces the initial amount of structured cabling. It is often recommended for its rack-at-a-time deployment, ability to limit the use of copper cabling within racks, support for east-west (ie, server-toserver) traffic and rack-level management capabilities. Both TIA 942-compliant structured cabling and ToR have advantages and disadvantages. When selecting the cabling configuration to best meet the needs of the data centre, it is important to examine the impact that structured cabling and ToR have on overall total cost of operations, as well as other trade-offs.

Manageability considerations With structured cabling, patch panels that mirror switch ports and server ports connect to corresponding panels in one or more central patching areas or zones via permanent (or fixed)

DATA CABLING

links. Also referred to as distribution areas, these patching areas may be located at the end or in the middle of a row of cabinets. Moves, adds and changes (MACs) are accomplished by repositioning patch cord or fibre jumper connections at the central patching area. The fixed portion of the channel remains unchanged and switches and equipment are left untouched and secure. This creates an ‘any-to-all’ configuration where any switch port can be connected to any equipment port. Furthermore, structured cabling can be field terminated to any length to maintain a clean, slack-free appearance. In a ToR configuration, switches at the top of each rack connect directly to the servers in the same rack, requiring all changes to be made within each individual rack (or cabinet). This eliminates the use of central patching and reduces the amount of structured cabling in the data centre. MACs in a ToR configuration can be more complicated and time consuming - especially in large data centres with hundreds of cabinets. Changes must be made in individual racks or cabinets, rather than at one convenient central patching area. Identifying the specific rack or cabinet requiring the change can be a complicated process. ToR can be a solution for data centres where individual racks of servers and their corresponding switches need to be managed as their own entity or segregated by application. ToR does not allow network administrators to keep switches separate from server administrators, which can be problematic when these groups manage switches and servers separately and when switches must remain protected for security purposes.

equipment upgrades. The core physical layer infrastructure or the fixed portion of the cabling channel is typically installed once, as long as the minimum standards recommended fibre and copper cabling are used. In a ToR configuration using small form factor pluggable twinaxial cable assemblies, distance between the switches and the servers is limited to a length of seven metres in passive mode. While this is not a problem if each rack will always be managed as an individual unit, these short lengths can restrict the location of equipment if needs change. Structured cabling lengths can be up to 100 metres, allowing flexible equipment placement.

Interoperability concerns

Interoperability and the open systems concept is the ‘bedrock’ of cabling industry standards. Data centre managers expect and value interoperability to fully leverage their existing cabling investment by ensuring performance and a competitive market regardless of which vendors’ equipment and cable designs are selected. Unfortunately, some switch vendors now require their proprietary cable assemblies for connecting ToR switches to servers when using small form factor pluggable twinaxial cable assemblies. Some ToR switches are designed to check vendor security IDs on cables and either display errors or prevent ports from functioning when connected to an unsupported vendor ID. While this helps ensure that vendor-approved cable assemblies are used with corresponding electronics, it can limit data centre Scalability and upgrade considerations design options by locking data centre managers into a propriA widespread switch upgrade with ToR impacts many more etary solution.

TESTING IN THE ENTERPRISE: HOW HARD CAN IT BE?

Tim Jefferson General Manager, Enterprise Solutions, Spirent

You get a patch or an upgrade for your firewall from the vendor. They say it fixes that one problem that’s been bugging you for the last few months. But you can’t just install the update, right? You have to test it first.

o problem. You upgrade the backup firewall, throw together a few scripts to hit it with traffic and use a packet sniffer to make sure the right stuff comes out the other end. Simple, right? Maybe not. Before you go live, you have to make sure that the patch: 1. fixes the problem, 2. doesn’t break anything else, and 3. still gives you the throughput and performance you need. Will your script verify the function and performance of all the features your organisation depends on? Will it generate stateful TCP conversations? Both inbound and outbound traffic flows? SSL in an HTTPS flow? As you dig deeper, you find more questions than answers. If you find a problem, will your vendor accept the results of your homegrown test scripts? How do you know the problem isn’t with your scripts instead of the device? For example, can you demonstrate how much transaction latency is created by the traffic generation process and how much by the firewall? The testing process is more than just discovering performance limits. Testing is about delivering the assurance and confidence that a sys-

tem will perform at a given level. At the core of testing is the concept of acceptance, which can be achieved by testing for real-world scenarios. Vendor data sheets promise that their network devices will perform at very high speeds. However, real-world performance depends on how the device is used - what the actual traffic flows are on the hardware and software in use. And despite what the data sheet says, one thing you know for sure: they didn’t test it on your network. Your network was designed specifically to address the needs of your organisation, its geographic reach, its mix of users, applications and mission-critical processes, its requirements for response time, throughput, redundancy and failover. Enterprise network and application testing: how hard can it be? Actually, if you have the right tools, it can be fairly painless.

he ethernet has been connecting PCs, servers, switches and printers for more than four decades. In the space of 40 years, it has undergone a remarkable series of evolutions that have enabled it to deliver so much more - opening the way for applications such as keyless entry systems, videoconferencing, IP security cameras and voice over IP (VoIP) to mention but a few. The network is now busier than ever and while the organisations are maximising all available bandwidth, they are not necessarily maximising power efficiency. Not many businesses recognise that PoE

30 ECD SOLUTIONS - JULY/AUG 2013

is capable of far more than simply feeding power down a cable. It offers a range of advantages including cost and power savings, business continuity, improved control and better system backup.

Cost savings One of the main benefits of PoE is the cost savings. Using ethernet to deliver power reduces the time and cost of installing separate cabling, AC (alternating current) outlets and wall sockets. Plus it eliminates the need for a dedicated UPS for individual devices connected to the ethernet.

Green credentials Whether motivated by environmental concerns or rising energy costs, most business users have good intentions to ‘go green’ and reduce power consumption. We’ve made some headway, as evidenced by the increasing number of people who turn the lights off as they leave their office in the evening. Yet the vast majority of people don’t think twice about leaving phone chargers or laptop power adaptors plugged in, even when the device is not using the power source. How many offices can switch off networking or networked equipment like wire-

less access points, IP phones or surveillance cameras? Probably one in a million. This is where PoE comes into picture. PoE-powered devices can be powered on or off remotely, giving far greater control while maintaining the level of high security that devices like surveillance cameras need. Powering off selected devices ensures you only pay for power that you’re actually using. PoE can provide power to VoIP phones for emergency use and enables a business owner to power down phones at selected times simply by using software controls, saving the business energy and money. Take, for example, a company with 200 employees using VoIP phone systems across the business. Each phone handset consumes between 2 and 7 W of power each day when not in use. If the business uses PoE to power down equipment for 12 hours overnight, on weekends and during personal and public holidays, it could save as much as 8736 kWh over the course of a year. In the process, it would reduce the company’s annual power bills by more than $2500.

Access to difficult locations PoE-powered devices require less cabling compared to AC-powered devices. They are, therefore, easier to install and replace, and more convenient to use. What’s more, fewer cables results in a cleaner look. With a PoE adaptor there’s no need for an AC outlet at the location of the endpoint. PoE also provides easier access to hard-to-reach locations or where there is a lack of space for power deployment, such as external walls or interior ceilings. In locations such as this, a business won’t have AC power, but may have devices that require power. PoE eliminates the need for high-voltage cabling.

Maintaining an uninterruptible power supply (UPS) Nobody wants to run the risk of losing business data, which is why most businesses carefully protect their access to traditional power through the deployment of uninterruptible power supply (UPS) devices. What is not so widely realised is that with

www.ECDsolutions.com.au

PoE, businesses can use UPSs to protect much more than a server. Consider an IP phone system. In the event of a power cut, all IP phones plugged into a wall outlet will lose power. If the endpoints are powered through a central PoE switch, however, and if the PoE is plugged into a UPS, power is maintained and the system is protected.

Control over power and the network It’s a fact of life that at some stage IT equipment may stop working and enter a state where it cannot listen to NMS commands. This is where PoE boasts significant advantages over AC. When PoE-powered equipment hangs, the IT administrator has greater control and can easily power cycle the equipment. PoE also enables better control over the network. A small business owner can make power-rationing decisions centrally for all PoE devices by configuring through the switches. In the case of a fully integrated system where PoE is used to power access points and door entry and intercom systems, SMEs can develop a management system intelligent enough to power down PoE devices when the property is empty.

Futureproofing the network With standards improving all the time, devices are becoming more energy efficient and networks are becoming more powerful. The result? We’re not that far off being able to manage and power the entire IT system from servers to user devices as a single entity. That’s great news for resource-stretched SMEs or for organisations where people regularly leave their power supplies plugged in, draining power even when their laptop battery is fully charged. PoE will continue to gain momentum as additional compatible devices are developed and new applications emerge.

CASE STUDY

Fire-resistant cable technology to improve safety

able manufacturer Olex, in partnership with CSIRO, has developed a new technology for making fire-resistant electrical cables. An Australian-developed plastic cable coating material that transforms into fireproof ceramic in a blaze has the potential to be a genuine lifesaver. Ceramifying polymers have a host of potential applications in fire prevention in buildings, ships, vehicles and industrial and defence equipment. The story began when Olex Australia challenged the multidisciplinary CRC for Polymers team to design a revolutionary fire-resistant electrical cable that could keep electricity flowing in a fire at temperatures above 1000°C. Conventional polymers (a type of plastic), which cover electrical wiring, typically melt between 100 and 200°C and disintegrate completely at about 300°C. The solution was to combine the properties of a polymer with those of a ceramic, allowing the standard operation of the system under normal conditions, while transforming to a ceramic in the event of a fire. As the polymer melts and disintegrates in the heat, at the same time the ceramic forms a solid protective insulating layer, preventing short circuits and enabling circuit integrity. During a fire, the cable’s ceramic insulation maintains the integrity and continuity of circuits for building safety systems such as emergency lighting, alarms, pumps and fans that are vital for safe evacuation and firefighting. In the event of a fire, this unique technology will significantly

improve safety. The cables’ ceramic shield maintains the integrity and continuity of circuits for essential services such as alarms, pumps and fans that are vital for safe evacuation and firefighting. When these cables are exposed to fire, the polymer melts. But instead of disintegrating, additives within the plastic react during combustion and solidify to form a ceramic layer over underlying electrical wires.

Easy pushbutton programming ensures quick use. Additionally, the sensor features scratch-resistant precision lenses for minimum sensitivity to scattered light. Infrared temperature measurement is used where temperatures can only be measured indirectly (ie, without contact). The sensors detect infrared radiation emitted and convert them to an output signal. If the detected temperature is above the set switching threshold, the switching output is set and the switching status of the LED is displayed. The switching thresholds and output configurations can be set and be easily reproduced by means of the button and the display. Clearly visible LEDs always indicate the switching status.

Standardised, certified modular data centre Rittalâ&#x20AC;&#x2122;s RiMatrix S, a standardised, certified modular data centre, is an alternative to individual data centre construction, reducing the planning and implementing costs of traditional data centres. The data centre is claimed to have a delivery time of six weeks, as a consequence of the data centre modulesâ&#x20AC;&#x2122; high level of standardisation. RiMatrix S is assigned in blocks.

If the server modules are used in conjunction with a cooling unit from Rittal, the system reportedly offers a PUE (power usage effectiveness) of up to 1.15. For each kilowatt of power that the servers take up, 15% of additional energy is used; for instance, for climate control and uninterruptible power supply, Rittal says. The system is flexible: users can connect their own resources via the clearly defined transfer points for energy, climate control and network. According to Rittal, if the data centre is installed in the userâ&#x20AC;&#x2122;s facilities, all the components are in the correct order and can be mounted immediately, giving a functioning infrastructure that allows applications and services to be used within a short time. This can minimise the time to market. The modules are available in versions with six (Single 6) or nine (Single 9) server racks, which can be combined to form larger units. It draws on the existing Rittal IT modular product line, incorporating predefined modules, including server and network enclosures, climate control and power supply. Administrators can use the same monitoring and control tools with each RiMatrix S module, even if the modules are mounted at different locations. This can reduce training time, make service and IT management easier and free up administrator resources. Rittal offers a RiMatrix S Configurator on its website, where clients can calculate whether speed, installation and standardised processes outweigh any possible disadvantages from the reduced customisation.

Online cable testing system EA Technology has launched an instrument for identifying defects in live cables of distribution voltages. The CableData Collector works by testing for partial discharge (PD) activity - small discharges that result in damage to the cable, and if left unattended will lead to insulation failure. The instrument quickly detects PD activity in live cables by measuring radiofrequency currents. It works with most types of single- and three-phase insulated cables at distribution voltages, up to several kilometres in length. Information about PD activity is recorded by the CableData Collector hardware and can be sent to EA Technology for expert analysis. Alternatively, users can purchase EA Technology’s software package to perform their own data analysis. In either case, they will have access to clear reports on cables affected by PD activity and recommendations for remedial action. CableData Collector instruments are supplied as complete, readyto-use kits, with radiofrequency current transformers (RFCTs), cabling, USB-powered data collection unit and carry case, together with optional software, training and factory technical support. Kits are also available for rental, or EA Technology engineers can provide cable testing as a site service. EA Technology www.eatechnology.com

ACMA cabler competency requirements

Paul Stathis, South Pacific CEO

The changes to the ACMA’s competency requirements for Registered cablers addresses concerns within the cabling industry that cablers may not have the appropriate skills required to perform specialised cabling work (ie, beyond the scope of a base Registration) for the current and emerging cabling environment. This means from July 2014, cablers will need to have the necessary competencies in whatever specialist field of cabling they’re working in. Until now, specialist cabling such as optical-fibre, coaxial and structured cabling could be installed by Open Registered cablers without any specialist competencies (although these were readily available and cablers were encouraged to acquire them through further education). However, they will no longer be voluntary as of July 2014. Put simply, if you work on specialist cabling, you’ll need proven competency in that speciality. If you don’t work in a particular speciality, you won’t need that competency. For example, if you install Category 5 or 6 data cabling, you’ll need a Structured Cabling competency added to your Open Registration. If you only install telecommunications cabling, your Open Registration will cover this and you won’t need additional competencies. If you decide to install structured cabling in the future, you will need to acquire that competency. Consider the following scenarios that best describe your circumstances to determine what you need to do before July 2014: Open Registration with no endorsements: If you’re not installing specialty cabling, you won’t need to do anything extra. Simply maintain your Open Registration and it will remain as is. If you’ll be working on structured, fibre or coax cabling as of July 2014, you’ll need to acquire the appropriate competencies through training and/or assessment. Open Registration with Cat 5/structured, fibre or coax endorsements: Holding any of these old endorsements means you won’t necessarily need any additional training in that specialty, as they’re equivalent to the corresponding new competencies. When renewing registration after July 2014, your current endorsements will be listed as competencies. To do other specialist cabling, you’ll need to acquire the relevant competencies through training and/or assessment. Restricted Registration: Restricted cablers must attain the new Broadband competency if they want to perform specialist cabling work. This is for residential premises point-to-point work only and doesn’t apply to Open Registered cablers. Endorsement training modules won’t be recognised after June 2014. To acquire competencies from July 2014, cablers will have to be assessed by registered training organisations (RTOs) as ‘competent’ for cabling specialties. Recognition for Prior Learning (RPL): RPL processes and decisions are performed by RTOs, who are required by the ACMA to ensure that credit for prior learning - vendor or classroom-based training or industry experience - is accurately mapped to relevant competencies. Cablers with vendor certification should notify the RTO as part of their RPL assessment. Vendors will now have to align their certification training to competencies if they want them ACMA-recognised - as only RTOs will be able to issue formal certifications and statements of attainments. If you need training to secure competencies, ACMA-approved training providers are listed at: www.brca.asn.au/pdfs/CPR%20 Accredited%20Training%20Providers.pdf. www.bicsi.asn.au

POWER MANAGEMENT

REVEAL THE POTENTIAL OF YOUR POWER NETWORK

As energy-intensive businesses continue to operate in today’s constrained environment, the need for effective energy management is greater than ever. Due to Australia’s strong economic growth, some sectors are still seeing an increase in electrical energy emissions, as shown in the National Greenhouse Accounts released in April.

lthough power is a critical element for any business, no matter what industry, it needs to be reliable and economically sustainable. With organisations increasingly using more power, managing it efficiently can be a challenging task. Traditional power-management solutions such as switch gear, circuit breakers and metering devices are all key elements to managing energy usage. However, relying solely on these to keep track of usage could mean that businesses miss the opportunity to run their operations even more efficiently. Poor power management in a business presents a number of risks. Without a clear understanding of what state the electrical infrastructure is in, there is no visibility of what is happening inside a facility in terms of energy usage. This could lead to reliability issues with power availability if problems are not tracked and monitored, which could have a huge impact on business if power fails. Additionally, without visibility across the infrastructure, businesses are unable to identify where money is being spent on energy. Organisations regularly face challenges in maintaining or even increasing profits. Energy is a significant and often overlooked expense that can represent a substantial area of opportunity.

www.ECDsolutions.com.au

Once energy usage and its related costs are exposed, the potential for releasing large amounts of wasted money can be realised. Reducing these costs can help firms survive tough times in the short term while reducing financial risk and strengthening competitive positioning into the future. Energy management is one approach in which businesses can easily keep track of usage and monitor spending more effectively. The concept of energy management can be a daunting task, especially when it means moving away from traditional or wellknown tools and systems that are already in place. With multiple elements such as maintaining power system reliability, complying with evolving emissions regulations and reducing the risks posed by volatile energy prices, energy management can seem nearly impossible to achieve. However, power management doesn’t need to be a difficult task. Combined solutions are available that allow businesses to improve operational, cost and energy efficiencies, increase reliability and availability of power and improve asset optimisation. Moving away from traditional power-management tools towards more complete solutions that offer an integrated, fully scalable and

POWER MANAGEMENT

reliable power-management system allows businesses to improve the electrical distribution systemâ&#x20AC;&#x2122;s reliability, from medium voltage to final distribution. This is done by using advanced software that provides central monitoring, control and analytical functions, combined with customised applications where needed. Opting for a complete mechanical, electrical and digital system that is modular and interoperable allows improved continuity of supply and enhanced safety for people and equipment. By using the information that these systems provide, businesses have the opportunity to make decisions on how best to minimise costs and energy use without affecting overall business operations. This increases the financial and operational efficiency of an enterprise, which is one of the key limitations of traditional power-management solutions. When choosing a power-management system, a key consideration is compatibility with third-party systems. Businesses may have some traditional management solutions already in place, so third-party integration should be a priority in order to seamlessly integrate and leverage all systems. However, not all businesses operate in the same way and infrastructure varies, meaning power-management requirements will be different. It is important that a solution is flexible in order to adapt to unique business requirements as well as the changing environments within organisations. A key consideration should be to ensure power-management systems are fully integrated, complete solutions that offer flexibility to meet individual business requirements and help solve challenges. For example, if a data centre was concerned about escalating energy usage, by using a flexible solution it could implement predesigned power-management solutions that include the ability to verify and track power usage effectiveness (PUE), in addition to

resolving issues such as battery maintenance, run-time variations and integration with fuel-management systems. Using an advanced power-management system means the data centre would have the necessary information to identify where and when energy is being used and make informed decisions about the best solutions to reduce power consumption and save money on operating costs. When considering the capabilities of a power-management system, it is important that businesses are able to quickly and easily monitor, analyse and control the entire network to ensure visibility. Power-management solutions that comprise integrated hardware, communications and software components that unite disparate power infrastructure elements are one way a network can be closely tracked and monitored. By selecting seamless technology that underpins the solutions, both management and front-line personnel have the personalised tools needed to make timely, cost-trimming energy decisions without sacrificing reliability or operational efficiency. In a world where businesses are constantly searching for a competitive advantage, complete power-management solutions have the ability to support this by providing a more advanced system compared to traditional power-management solutions. When implementing an advanced system, businesses have the potential to achieve energy savings of up to 30%. Power management is a concern across all industries, and an issue that is unlikely to disappear in the future. It is important for all businesses to be mindful of the power they use, and consider options that give them complete visibility. Not only will it improve on cost savings, benefiting the business overall, but it also means regulations can be adhered to in the future.Â Schneider Electric (Aust) Pty Ltd Contact info and more items like this at wf.net.au/U516

NEW ENERGY MANAGEMENT STANDARD

Today, more than ever, reducing energy use is a crucial issue for the success of any business. Managing energy consumption can help a business beat rising energy costs, comply with greenhouse gas legislation and improve its reputation.

SO 50001 is an international standard that equips businesses with the latest best practice in energy management. It was developed by energy management experts from more than 60 countries across the world. ISO 50001 will help businesses to: • Understand their energy usage. • Create action plans, targets and energy performance indicators. • Identify, prioritise and record opportunities for improving energy performance. • Save money on energy costs. According to BSI Group, ISO 50001 can help organisations of all types - public sector, governmental, corporations, small or medium-sized businesses across all sectors and countries save money by reducing their energy costs. Features and benefits of ISO 50001 include: • Reduce costs: reduce energy costs via a structured approach to identifying, measuring and managing energy consumption. • Reduce GHG emissions: meet current or future voluntary and/or mandatory energy efficiency targets or greenhouse gas emission reduction legislation and stakeholder expectations now and in the future. • Secure energy supply: understand the business’s energy risk exposure and identify areas of the organisation at greatest risk. • Improve business performance: drive greater productivity by systematically identifying and prioritising the most

TRANSITION TO A LOW -EMISSION FUTURE The HVAC&R industry is often described as a notoriously fragmented - and sometimes invisible or overlooked industry. However, recent developments such as the carbon-equivalent levy and the ever-increasing need to lower emissions have forced the industry to pull together and find its voice. This voice has taken the form of the proposed PRIME Roadmap for HVAC&R, a document that, although still in its early stages, is slated to act as a guide for those who influence the future of HVAC&R - meaning everyone from ‘the man in the van’ to top consulting firms.

he proposed PRIME Roadmap for HVAC&R was released earlier this year, during the Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH) Industry Summit 2013. Compiled by those in the industry for those in the industry, PRIME sets out the main priorities that need to be addressed in order to lower emissions caused by the HVAC&R industry. In the lead-up to the AIRAH Industry Summit 2013, AIRAH, with the assistance of many of the stakeholders who attended, developed a 150-page draft discussion paper. It was from this discussion paper, says AIRAH CEO Phil Wilkinson, M AIRAH, that a far more important document emerged: that of the proposed PRIME Roadmap for HVAC&R. “PRIME represents the five pathways to transition to a low-emission future for our industry,” Wilkinson says. “All proposed solutions from the discussion paper have been divided into five categories: Professionalism, Regulation, Information, Measurement, and Emission abatement.” Wilkinson agrees that in many ways, the HVAC&R industry

50 ECD SOLUTIONS - JULY/AUG 2013

is still fragmented, a fact that makes progress towards lower emissions much more challenging. In order to overcome this challenge, the industry needs a strategy - which is where PRIME comes in. “The purpose of PRIME isn’t to immediately solve all of the issues faced by the industry or to mandate the essential steps that the industry must take to be environmentally and commercially effective,” says Wilkinson. “It isn’t that simple. But there is a need for a common voice, an agreed direction and a set of agreed pathways - all of which the draft road map represents.” The HVAC&R sector is both a significant consumer of energy and contributor to greenhouse gas emissions. An estimated 24% of Australia’s emissions are directly attributable to the built environment. Of that 24%, HVAC&R services are significant consumers - to the order of 30 to 50%. On top of that, 3-5% of Australian emissions are directly attributable to the refrigeration cold chain; and 1-3% of Australian direct emissions are attributable to refrigerant leakage.

www.ECDsolutions.com.au

EFFICIENT HVAC&R

‘Information’ recommends producing a “low-emission HVAC&R street directory” or IP repository, making all validated energy-efficiency information available in the one place. It also covers the need to increase awareness of life-cycle costing and the total-system design approach, as well as recommending training for architects and the development of ammonia-use fact sheets. PRIME’s ‘Measurement’ category covers benchmarking and rating tools, maintenance records, design standards, and the validation of product claims, among others. Finally, the ‘Emissions Abatement’ section looks at best-practice installation, codes and standards, leakage issues and the whole gamut of how emissions could be scaled down. THE NEED TO TRANSITION TO LOW-EMISSION HVAC&R HAS BECOME SELF-EVIDENT. BUT IT’S NO LONGER A QUESTION OF ‘WHY’ - THE FOCUS IS NOW ON THE ‘HOW’ AND ‘WHAT’ OF LOW EMISSIONS, WHICH IS WHAT PRODUCED THE PRIME ROADMAP.

©iStockphoto.com/MADDRAT

Wilkinson says that with these figures in mind, it’s clear that the HVAC&R industry needs to make this transition to low-emission practices and technologies. “Governments are demanding it, the environment needs it, and society is expecting it,” says Wilkinson. The PRIME Roadmap offers a clear and detailed way forward, with executable actions that will lead to lower emissions and a more skilled industry, Wilkinson says. Within the five categories that make up the letters of PRIME, individual actions are ranked by priority and potential for reducing emissions. Under the ‘Professionalism’ category, PRIME earmarks actions such as the formation of a unified “umbrella group” of industry representatives, as well as the need to invest in group training schemes and more apprenticeships. The ‘Regulation’ category covers actions such as logbook programs and shared intellectual property (IP), as well as mandatory coefficient of performances (CoPs), among others.

But pulling such a comprehensive document together wasn’t easy. In the lead-up to the summit, AIRAH asked industry stakeholders to comment on the industry issues raised in the draft discussion paper created earlier in the year, and to focus on potential solutions. “From there, these solutions were then allocated into the five PRIME subject areas,” says Wilkinson. “They were further divided by priority, complexity, potential for emission reduction, and resources that might be contributed. “The development of the proposed PRIME Roadmap brought the HVAC&R industry together, and now there is a groundswell of support for the pillars underpinning it,” Wilkinson says. “Our vision is for a highly skilled and professional Australian HVAC&R industry that is safe, cost effective and environmentally effective.” Wilkinson says consolidating a multitude of viewpoints and bringing the industry together to discuss it represents a formidable task. “The need to transition to low-emission HVAC&R has become self-evident,” Wilkinson says. “But it’s no longer a question of ‘why’ - the focus is now on the ‘how’ and ‘what’ of low emissions, which is what produced the PRIME Roadmap.” For now, the proposed PRIME Roadmap for HVAC&R is continuing to be refined, with issues such as trends, resourcing and timescales still being considered by stakeholders and industry representatives. AIRAH board director Bryon Price, M AIRAH, oversaw the development of the road map, alongside other key stakeholders and contributors. “Our industry has influence and control over a significant component of mankind’s impact on the Earth via emissions and carbon usage,” Price says. “We have the responsibility and capacity to do something about this. But we also have the responsibility to plan for an HVAC&R industry that is productive and prosperous. We think PRIME could be a pivotal component in accomplishing this.”

LIGHTING DESIGN

MOTOKO ISHII LIGHTS UP SPARC 2013 Alice Richard

Can lighting design have a social, environmental and cultural impact? Motoko Ishii believes it can.

peaking at SPARC International Lighting Event 2013, Ishii gave a brief history of Japanese lighting design from the 1970s to the present day, describing her design aesthetic and the impact good lighting can have. Returning to Japan from working in Europe in the late 1960s, Ishii established her lighting firm, the Ishii Motoko Design Office, becoming the first freelance industrial lighting designer in Japan at the time. Not only was she a pioneer in her field, she was also a female designer in a heavily male-dominated industry, at a time when a woman’s place was considered to be anywhere but on a construction site. Ishii’s work on Tokyo Tower earned her international attention. To address rapidly dwindling ticket sales to the structure, Ishii was hired to redesign the tower’s lighting arrangement. The result was unveiled in 1989. Positioned in and around the tower’s frame, 176 floodlights illuminate the structure. From 2 October to 7 July, sodium vapour lamps are used to bathe the tower in a warm orange glow. From 7 July to 1 October, metal halide lamps throw a cool white light over the tower. Ishii tries to express a sense of season in her lighting design, as seasons are important to Japanese culture. The choice of warm colours and warm whites during the winter months serves to offset the cold weather, Ishii says, while the cool white light used in summer provides a foil to the hot weather. Despite taking her work seriously, Ishii also injects a sense of playfulness into her designs. The Tokyo Tower, and many of her other designs, are lit in different colours for special events and holidays. The Tokyo Tower received a ‘diamond veil’ for its 50th anniversary: 276 lights in seven colours distributed across the tower’s four faces gave the effect of a glittering diamond. Just this week, Ishii said, the Tower was lit with blue to wish the Japanese soccer team luck.

54 ECD SOLUTIONS - JULY/AUG 2013

Ishii has worked extensively lighting up important Japanese buildings and monuments since establishing her business. In this instance, Ishii believes lighting has a social, not just a practical purpose. Lighting structures that were previously invisible at night attract more tourists in the evening, which stimulates spending and can enliven areas of a city. Highlighting historic buildings and monuments can also strengthen and promote cultural heritage, Ishii said. While lighting draws attention to a building at night, Ishii says it’s important that the lighting design doesn’t detract from a building’s beauty during the day. Particularly with traditional buildings, she says it’s important that the lighting hardware be placed in such a way as to be invisible at best, or unobtrusive at the very least. Ishii takes a structure’s surroundings into consideration when designing lighting. For instance, she designed the lighting for the Shanghai World Financial Center to be deliberately ‘quiet and elegant’ in contrast to the busy, loud Shanghai skyline, bringing a Japanese aesthetic to the Chinese city. Ishii was commissioned to design the lighting for the recently reopened Kabuki-za theatre in Tokyo. The building’s facade is illuminated in a white light that varies in warmth with the seasons and time of day. The theatre’s traditional roof tiles are lit from above with LED lighting on the top floor of the adjoining 130 m Kabuki-za Tower, designed to resemble moonlight. Despite the extensive lighting arrangement, the use of LEDs makes the lighting efficient to operate: the electricity cost comes in at around $1.50 per hour of operation. Most of Ishii’s recent work employs LEDs, solar panels and often wind power. While the solar panels don’t produce electricity for a lighting arrangement when it’s needed, Ishii said they feed clean energy back into the grid, which then supplies mains electricity for the lights’ operation at night. Ishii’s presentation was an interesting insight into the history of Japanese lighting design - and its future.

Directional antenna Narda Safety Test Solutions has extended the range of application for its Interference and Direction Analyzer down to very low frequencies with a new loop antenna. The antenna is particularly suitable for detecting interference caused by switching power supplies or data transmission over electricity supply lines. The new loop antenna for the Interference and Direction Analyzer IDA-3106 covers a frequency range from 9 kHz up to 30 MHz. Its typical antenna factor of 47.5 dB(1/m) at 1 MHz gives it unusually high sensitivity. This makes it particularly suitable for tracing defective or poorly screened switched mode power supplies or electrical controls that generate interference fields, for identifying interference due to data transmissions made using the power line carrier technique or for demonstrating interference with other signals in the very low frequency range (VLF), eg, using the time signal of the DCF77 transmitter.

shows the bearing on a polar diagram. The IDA calculates the position of the interference source from several bearing results and displays it automatically. Users can optionally display freely available electronic maps, so that the source can be traced right down to its location in a particular street, similar to a navigation system. The IDA provides a room plan that can be edited to enable localisation within a building, eg, in a conference room. The basis for finding the location of an interference source is provided by a GPS receiver in the measuring set and the electronic compass in the antenna handle, which determine the direction, elevation and polarisation. Antennas optimised for different frequency ranges are available; these can be attached horizontally or vertically to an ergonomically designed handle.

CASE STUDY

Managing disasters at the emergency operations centre

hen a natural disaster or major incident occurs, it is vitally important that emergency services personnel have a safe and secure base from which to manage their response and recovery operations. With this requirement in mind, the Queensland Government has constructed a new emergency operations centre to provide front-line staff with enhanced capacity to meet increasing operational demands and to support large-scale disasters. The Queensland Emergency Operations Centre (QEOC) houses the State Disaster Coordination Centre, State Operations Coordination Centre, 24-hour Emergency Management, Queensland Watch Desk, Queensland Ambulance Service (QAS) and Queensland Fire Rescue Service communications facilities, the Queensland Clinical Coordination Centre and the departmentâ&#x20AC;&#x2122;s Geographic Information Services. To e n s u re e ss e n t i a l services can perform their jobs to minimise the risk and impact of accidents, emergencies and disasters, the centre required a comprehensive, reliable electrical system, integrating lighting, heating, ventilation and air conditioning. The system had to be energy efficient, provide natural ventilation where possible and offer the highest practical occupant satisfaction rating, noting that many of the occupants would be working round the clock in very stressful situations. Electrical contractor Mark Bridger from Integrated Systems Group, a Clipsal Platinum Partner, was contracted to complete the integration of the project. Clipsal by Schneider Electric and Schneider Electric products were chosen for the project. The QEOC comprises a three-building data and communications centre and a commercial office building. The centre has been designed to accommodate 60 staff during normal operations and 200 staff at peak demand periods. Targeting a five star Green Star rating for the project, energy efficiency was a priority for the client. To help meet this objective, a Schneider Electric ION enterprise energy management system was fitted at the site. The PowerLogic ION meters can monitor and log devices, record analog and digital inputs, as well as send alerts to notify if there is a problem with the system. The energy metering is operated through the Schneider Electric BMS and the installation of the system, integrated into the Schneider Electric low-voltage switchboard and circuit breakers, ensures the Queensland Emergency Operation Centre complies with the standards needed to gain efficiency accreditations. In addition to the energy-efficiency reporting, the energy management system has also been utilised to rectify power quality issues at the site. Soon after the tenants moved into the building, they experienced power fluctuations, which were causing some concern. Through the ION enterprise system the cause of these fluctuations was identified and then resolved, saving the QEOC money and protecting their power requirements.

58 ECD SOLUTIONS - JULY/AUG 2013

Schneider Electric uninterruptable power supplies were also used in the project to ensure that critical equipment is still able to be used in the event of a power outage. Employee comfort is of the utmost importance, so a Clipsal by Schneider Electric C-Bus system with integrated lighting, blind control and light-harvesting sensors has been installed at the building to maintain a suitable working environment. General office lighting, which is controlled via Clipsal DSI dimmers wired through relays, has been dimmed to 90% output, while still maintaining an appropriate level of light in the area. This setting means that energy is being saved by not running the lights at full power. In the QAS communications centre, the light fittings are more than 10 metres above the floor. To reduce any downtime incurred when the lamps need replacing, the light fittings have been split into two groups of six channels. Only one group of six channels is needed at a time, and a push-button switch has been installed so workers can easily and quickly swap between light groups. This backup means that the first lighting group can be replaced in a prompt, but relaxed time frame. Each workstation has its own individual task lighting, operated via local motion sensors. After 10 minutes of inactivity at the workstation, the lights automatically switch off. Lights in the corridors between the communications building and the disaster management centre are controlled by a PE cell. Once the PE cell detects that natural lighting is below 200 lux, then lighting in the level-two walkway, the darkest walkway in the complex, is turned on. When the same PE cell detects that natural light has dropped below 100 lux, the rest of the walkway lighting is turned on. Similarly, a PE cell has been located on the roof of the communication building. When the PE cell detects higher than 2000 lux, all blinds on the north side of the building drop down. Workers can raise the blinds manually after this point if they would prefer natural light. The blinds will only drop automatically once every day. In addition to this, the blind controls within these areas are on a key-lockable switch. The C-Bus lighting has also been integrated into the Schneider Electric BMS system and a third-party security system. C-Bus links to the BMS via a BACNET gateway, with areas split into zones. Once any lighting group within a zone is on, a C-Bus command is sent to the BMS to turn on the relevant air-conditioning zone. Once all lighting groups within the zone are off, a C-Bus command is sent to the BMS to turn off the relevant air-conditioning zone. C-Bus integrates to the third-party security system via RS232 connections. Once a signal is received from the security panel indicating that the building is armed, C-Bus then turns off all lighting groups. In the event of a security breach, C-Bus turns on all lighting within the building. Clipsal Australia Pty Ltd Contact info and more items like this at wf.net.au/T979

TOP SIX PLACES FOR ENERGY LOSSES IN COMMERCIAL BUILDINGS A considerable amount of energy loss in commercial buildings is temperature related. An obvious issue is hot or cold air leaks, but many other systems and pieces of equipment also waste energy in terms of heat.

nlike regular digital cameras that capture images of the visible light reflected by objects, thermal imagers create pictures by detecting infrared energy or heat. The thermal imager then assigns colours based on the temperature differences it detects. With a small amount of training, most people can use a thermal imager to readily spot abnormal heat flow patterns and follow the heat trail to find the source of the energy waste. The technique works best when used by people who already possess a good working knowledge of the structures and systems being scanned so that they can better interpret the temperature variances they see on camera. Fluke Australia has provided a list of the top six places to look for energy losses in commercial buildings together with details on how to detect these leaks using a thermal imaging scanner.

1. Building envelope The ‘building envelope’ refers to the building structure as well as the climate controls within it. The envelope is what separates the outside environment from the inside and it’s frequently imperfect. The problem with building envelope inspections is that the degree of temperature variance detected may often be very small, only a few degrees in some cases. The best time to scan is during a heating or cooling season when there is a large difference in temperature. Similarly, beware of solar loading, wind, precipitation and other environmental factors which could mask or distort potential problems. For instance, be careful to understand the direction and amount of heat flow when scanning an exterior wall if the sun is shining on it.

What to scan • Roofs - Wet roofing insulation loses much of its R-rating. This means heat can escape or enter the building much easier through wet insulating materials. In addition to looking for moisture issues, scan the roof surface and follow temperature differences to possible air leak entry/exit points. • Walls between conditioned and unconditioned spaces, including outside walls - Due to the natural flow of air with different temperatures, significant air leaks tend to occur at the top and bottom of conditioned spaces, where air either enters or escapes a structure. • Construction joints and connections - For example, at floor slabs that extend outdoors there are often heating or cooling losses by conduction through the slab. • Penetrations of the building envelope such as pipes, conduits and chimneys - Uninsulated or unsealed gaps often exist around roof and wall penetrations. • Door and window frames and seals - Locate air leaks around windows and doors caused by worn or missing seals.

2. Boilers Boilers are the heart of steam and hot water heating systems.

What to scan • Refractory and insulation - Thermal imaging makes the in-service monitoring and inspection of the condition of refractory linings for performance issues possible. • Fan motors - As with motors in other applications, check for impeded airflow, electrical unbalance, overheated bearings and failing insulation.

THERMAL IMAGING

• Pumps - Look for hot bearings, leaking seals and, as with fans, motor faults. • Valves - Thermal imagers can identify blocked valves that are nominally open and leaking valves that are nominally closed. • Electrical connections - As with other kinds of systems, look for loose or corroded connections that increase resistance.

3. Motors and generators Electric motors are one of the biggest energy consumers in any facility. Overheating and malfunctioning motors and generators tend to indicate mechanical or electrical inefficiencies that lead to unnecessary energy use and sometimes even failure. Since generators are, in a sense, ‘reverse motors’, diagnostics are similar for both kinds of units.

What to scan • Airflow - In fan-cooled motors, restricted airflow can cause general overheating often manifesting itself on the entire housing. • Electrical unbalance - A common cause, a high resistance connection in the switchgear, disconnect or motor junction box can usually be pinpointed by an infrared inspection and confirmed using a multimeter, clamp meter or a power quality analyser. • Bearings - When thermal images reveal bearing housings with abnormally high temperatures, either lubrication of the bearing or its replacement is often called for. Beware that over-lubrication can cause abnormal heating as well. • Insulation - Look for higher than normal housing temperatures in areas associated with windings. For each 10°C rise over the maximum rated temperature of a motor, approximately half the life of the motor is lost due to insulation failure. • Electrical connections - As with electrical connections in HVAC systems, look for loose or corroded connections that increase resistance. Heat losses due to high-resistance connections means that your energy is being given off as heat instead of being used for useful work.

4. Steam heating systems Today, steam systems are more common in industrial settings than commercial settings, but some commercial buildings still use them for central heating.

Where to look and what to look for • Steam traps - Check traps using both thermal imaging and ultrasonic testing. Each technology works better than the other for certain traps and trap configurations. • Radiator coils - Check for obvious steam leaks in radiators and at all visible pipe and joint connections. • Steam lines and valves - Look for signs of leaks and blockages and for blow-by at valves that are supposed to be ‘closed’. • Condensers - Look for leakage of outside air, which reduces the condenser’s vacuum, thereby decreasing its efficiency.

5. HVAC system The heating, ventilation and air conditioning (HVAC) system is usually one of the biggest energy consumers within a facility.

www.ECDsolutions.com.au

What to scan • Ductwork and registers - Even the highest rated HVAC system wastes energy without a well-sealed duct system. With thermal imaging one can see the thermal pattern of air loss or gain in ducting and also monitor registers to determine whether heating or cooling output is optimal. • Fans and blowers - These mechanical elements are, of course, motor driven. In fans and blowers, mechanical imbalance will manifest itself in overheated bearings and other components. Thermal images of these systems can also identify shaft misalignment in couplings between the motor and fan. • Electrical connections - Loose or corroded connections increase resistance at the connection point, resulting in increased energy costs. • Compressors and coils - Regular inspections of the compressors and coils can also help reduce energy costs. A malfunctioning compressor can have a different thermal signature than a properly operating one. If coils are blocked or cooling fins are clogged, improper airflow and heat exchange can take place. This can greatly impact system efficiency and also further reduce component lifespan. A COMMON CAUSE, A HIGH RESISTANCE CONNECTION IN THE SWITCHGEAR, DISCONNECT OR MOTOR JUNCTION BOX CAN USUALLY BE PINPOINTED BY AN INFRARED INSPECTION AND CONFIRMED USING A MULTIMETER, CLAMP METER OR A POWER QUALITY ANALYSER.

6. Electrical system Many people don’t realise that electrical systems can actually waste money. As components degrade and resistance increases, waste occurs.

What to scan • Distribution panels - Check for unbalance in circuits and loose and corroded connections at breakers, contacts, fuse clips and buss work. • Transformers - Be aware that if the temperature of one electrical leg on a transformer is significantly hotter than the others, that leg may be failing. • Lighting control circuits - Check all wiring splices and connections at fuses, switches, in panels and at the fixtures. Be aware that thermal imaging can also be used to monitor low-voltage control circuits. As the price of thermal imagers has come down, it is claimed that most facilities can now recoup the cost of purchase in terms of energy savings within six months. Incorporating infrared inspection into regular maintenance in commercial buildings can provide significant energy efficiencies and also help to identify and prevent expensive failures.

Preventing electrical hazards

Malcolm Richards, CEO

As anyone associated with the electrical industry will know, working with electricity can be a high-risk and dangerous affair if proper precautionary measures are not employed. Yet we are continuing to see an increasing amount of unlicensed and illegal electrical work taking place across the country which has caused severe electrical injuries and in some cases even fatalities. Master Electricians Australia (MEA) has, in the past, urged contractors and tradies alike to employ stricter safety measures in the workplace following a spate of severe electrical safety incidents in New South Wales over the past year. However, government must also play its part in helping to deter illegal electrical work and make homes safer for families. Recently, MEA West Australian state manager Tony Mancini, on behalf of electricians across the nation, pushed for the WA Government to take unlicensed and illegal electrical work more seriously. It is our firm belief that governments should move immediately to protect consumers by: conducting a major media campaign highlighting electrical safety and the dangers of unlicensed electrical work; increasing safety switch protection to all circuits; requiring mandatory point-of-sale signage to use licensed electrical contractors for electrical installations and equipment; mandating electrical safety inspections when homes change hands; and establishing an electrical safety hotline for unsafe and unlicensed work to be reported. MEA is also deeply concerned with the increasing number of homeowners who carry out DIY electrical work on their homes. New Gumtree Australia research has showed 75% of Australian homeowners have attempted their own projects, with one in five resulting in a DIY disaster. This has reportedly resulted in Australians having spent an estimated $380m repairing these botched DIY jobs. These statistics show that government resources urgently need to be channelled into further educating the public on the perils of illegal electrical work, as well as directing more inspection resources into deterring do-it-yourself electrical work in homes. There needs to be continued education of the Australian public into the values of a Safety Certificate being received for any electrical work that has been undertaken on their homes. Safety switches should be installed on all circuits to prevent the risk of an electric shock should an electrical incident occur. With growing public awareness, we can greatly reduce the risk of an electrical safety incident. We should all be aiming for zero electrical accidents, fatalities or fires in our country. MEA is pushing for an electrical safety hotline with a dedicated advertised number to be established where illegal wiring or electrical work can be reported, and immediate advice and necessary steps can be taken to prevent a serious electrical safety injury. Finally, it is critical to remember that electricity can be unpredictable and working with it is a tricky business that is best left to the professionals. www.masterelectricians.com.au

chemical, chemical, food processing and pharmaceutical applications, and for remote panel installations on service trucks in the oil and gas industry. Because they are vapour actuated, the custom-made thermometers are not subject to error due to ambient temperature variations along the capillary tube, so they provide highly accurate readings above and below ambient conditions. These thermometers indicate media temperature using a temperature-actuated liquid in the sensing element. As the media temperature increases, the capillary fill fluid vaporises, increasing pressure in the Bourdon tube to activate the movement and pointer for proper indication. The thermometers come in 2½, 4, 4½ and 6″ sizes, from -40 to 60°F/C through 100 to 350°F/C. They are available with a brass or stainless steel case, with bottom, back or lower back connections.

OPTIMISING VOLTAGE

TO IMPROVE EFFICIENCY

Sam Czyczelis*

Australia has a particular problem with overvoltage and voltage optimisation is a solution to reduce energy consumption and carbon emissions. This article explains how the various types of optimisation systems can deliver cost savings and reduce significant tonnes of CO2.

oltage optimisation is a technique that has a significant impact on energy consumption because it brings the voltage supplied by the grid in line with what is actually required, and reduces losses in electrical equipment. Voltage optimisation can help businesses reduce annual energy consumption by 12-15% or more.The statutory electricity supply range for Australia is 230 V +10% to -6%, which means that electricity suppliers are required to provide a voltage level that is between 253 and 216 V. Therefore, the supplier will distribute electricity at 253 V and the voltage decreases over distance. On average, is it received from the grid at 242 V. Given that most electrical equipment manufactured for Australia is designed to work most efficiently at 220 to 230 V, any incoming power that is higher than this level is wasted energy and means companies are paying for power that is not required and not used. Voltage optimisation works best on inductive loads - motors and lighting for example - and significant savings can be achieved on motors in particular, especially if these are not loaded at 100% of their capacity for 100% of the time. Voltage optimisation effectively reduces the voltage to an optimum level, whereby all the equipment operates correctly but consumes less power in the process. These systems should also offer improvement in power quality by balancing phase voltages, cancelling damaging harmonics and transients from the electricity supply and reducing the reactive power, hence improving power factor.

www.ECDsolutions.com.au

Overvoltage means that energy consumption is not only higher but, as a result, the life span of equipment is shortened. Installing a voltage optimisation unit leads to reduced maintenance costs as less demand is placed on electrical equipment. There is nothing to be gained by operating equipment at a voltage higher than it was designed for; quite the contrary, as overvoltage will significantly reduce the life expectancy of most equipment. Generally, voltage optimisers will deliver between 12-15% savings. However, the most efficient solutions can save up to 26% of total electricity consumption and related CO2 emissions without compromising the supply to electrical equipment. Other benefits of installing a quality voltage optimisation system are: helps protect against damaging transients (power spikes) of up to 25,000 V; lowers the operating temperature of motors; provides an improved power factor by up to 20%. In addition, there are no moving parts and therefore zero maintenance on the unit itself. Sites that have their own HV distribution transformer, such as supermarkets, data centres, hospitals, hotels, education facilities and retail outlets, are more likely to benefit from a system that ensures voltage is supplied to a site at a constant level regardless of the input instability. This technology is recommended in these applications because when the grid voltage varies (often throughout the night as the load on the grid disappears), it is able to hold the site voltage at

the optimum level and maintain a high level of savings. The stabilised voltage output is a vital feature for sites with critical loads, secure data and important operations that require high levels of reliability and security. Older transformers have high levels of standing losses and the majority of modern transformers used on commercial sites use cold rolled grain oriented steel (CRGO) within their core, which still provides significant losses for buildings in comparison to amorphous steel. Businesses investigating this type of transformer should aim to achieve sustainability marks and high energy efficiency ratings through accreditations such as LEED (Leadership in Energy and Environmental Design) and BREEAM (Building Research Establishment Environmental Assessment Method). Along with savings in energy efficiency, LEED/ BREEAM also measure the characteristics of the products installed within a building and how much of a product can be recycled. A further important LEED/ BREEAM measurement is energy monitoring. It is important for transformers to come with a real time monitoring and targeting system, which enables companies to monitor energy usage as well as target further energy reductions. Conventional transformers generally utilise CRGO steel within their core. It is usually supplied by the producing mills in coil form and it has to be cut into ‘laminations’ that are then used to form a transformer core, which is an integral part of any transformer.

Amorphous metal contains ferromagnetic elements alloyed with a glass former. These materials have high magnetic susceptibility, with low coercivity and high electrical resistance. The high resistance leads to low losses when subjected to alternating magnetic fields. This results in transformers that use amorphous metal at its core, reducing standing losses, delivering greater efficiency and increasing savings. To ensure optimum savings and performance, a comprehensive analysis of a site’s power conditions should be completed before installation. As each building is different, with its own unique infrastructure and specific load requirements, a voltage optimisation strategy should be customised to each site. It is very importance to install a tailored voltage optimisation solution supplied by an experienced and reputable company. This will not only provide maximum energy savings and carbon reductions, but will also ensure that equipment will operate as efficiently as possible at all times, that the lifetime of equipment will be maximised, and that maintenance costs will be significantly reduced. *Sam Czyczelis is General Manager of Powerstar Australia, a wholly owned subsidiary of EMSc (UK).

The online system acts as a gatekeeper for the management of contractor workforces, providing online processing of contractor information to determine their risk level and compliance as well as capturing and tracking expiry of contractor documents such as insurance certificates and industry licences. Contractor companies register through the online portal and are assessed for their suitability and safety risk using an intuitive online form. Documentation is able to be sent and received between all parties, providing all stakeholders with a transparent communication pathway and record.
